Implementation of data usage callbacks.
NetworkStatsService will register data usage requests
and keep data usage stats scoped to the request.
There are different types of data usage requests
- scoped to a set of NetworkTemplate; these are restrictred to
device owners and carrier apps and allow the caller to monitor
all activity on the specified interfaces.
- scoped to all uids visible to the user, if the user has
android.Manifest.permission#PACKAGE_USAGE_STATS permission.
The set of uids may change over time, so we keep track of that.
- scoped to a set of uids given by the caller, granted that
the caller has access to those uids.
- scoped to the caller's own data usage. This doesn't require
PACKAGE_USAGE_STATS.

Introduce DEVICESUMMARY access level to NetworkStatsAccess.
Apps with PACKAGE_USAGE_STATS app op or READ_NETWORK_USAGE_HISTORY
granted can query the summarized device data usage (but not individual
uids running in other users or profiles).

Relax permissions around NetworkStatsManager APIs.
Currently, access to network usage history and statistics requires a
signature|privileged permission, an AppOps bit (associated with the
PACKAGE_USAGE_STATS permission), or device/profile ownership. Once
access is granted via one of these mechanisms, it generally applies to
any UID running in the same user as the caller.
This CL expands access as follows:
-Any app can access its own usage history with no extra requirements.
-Carrier-privileged applications can access usage history for the
entire device.
-Device owners can access per-UID breakdowns for usage. Previously
they could access the summary for the whole device, but not the
individual breakdowns.
We simplify the permission model by defining three access levels -
DEFAULT (own app only), USER (all apps in the same user), and DEVICE
(all apps on the device), and propagate these levels throughout.
Finally, this CL fixes an apparent bug in
NetworkStatsSerice#hasAppOpsPermissions - if the AppOp bit was in
MODE_DEFAULT, hasAppOpsPermission would always return false instead of
falling back to the PackageManager permission check.
